What began as a deadly multi-day tornado outbreak across the South expanded into a deadly flooding event across the East Coast Wednesday.

A deluge of rain along the Alabama-Florida line left people trapped on the roads and inside their homes Tuesday into Wednesday. The heavy rain stretched into the Mid-Atlantic Thursday, causing flooding and a landslide in a busy Baltimore neighborhood.

The heavy rain is part of the same system that spun up dozens of tornadoes during the weekend into Monday. Communities in Arkansas, Alabama, Mississippi and more are just beginning to pick up the pieces. In total, at least 40 people have been killed.

Below is a rundown of the outbreak's impact for each state:

Alabama

More than two feet of rain caused flooding problems for Gulf Coast communities in Alabama Wednesday just days after a severe weather outbreak brought multiple tornadoes to the state. There were at least 30 water rescues in the Mobile area alone.

Emergency managers say at least 240 homes were damaged or destroyed by the tornadoes and strong storms that swept through Alabama. The latest update from the Alabama Emergency Management Agency says damage is being reported in 31 of Alabama's 67 counties.

The greatest reported concentration of destruction occurred at the Smith Institute community of Etowah County, where between 100 and 150 homes were damaged or destroyed. Another 90 homes were hit in Blount County.

In Tuscaloosa, 21-year-old John Servati was killed when a tornado struck near Tuscaloosa Monday night. Servati and his girlfriend were hiding in the basement when a retaining wall was knocked onto him. He was a member of the swimming and diving team at the University of Alabama.

Limestone County Emergency Director Rite White told the Associated Press that two people were confirmed killed west of Athens, Alabama. in a mobile home park. That tornado left EF3 damage, as confirmed by a National Weather Service crew that surveyed the damage on Tuesday. The twister packed winds as high as 165 mph.

An EF1 tornado was confirmed in the Kimberly community, north of Birmingham.

Arkansas

A tornado that tore through at least 40 miles of central Arkansas Sunday night was rated the first EF4 of the year. NWS storm survey crews rated the tornado that killed 15 people in Mayflower and Vilonia an EF4.

Three of those deaths — a father and two daughters — occurred at a central Arkansas home of 11 people at the border of Pulaski and Saline County.

President Obama declared a disaster for Arkansas Tuesday afternoon, sending federal aid to assist in state and local recovery efforts.

Florida

The Florida Panhandle was hit with widespread flooding early Wednesday, washing away roads and forcing dramatic water rescues. Panhandle residents took to attics and rooftops to flee flooding caused by up to two feet of rain in a 24 hour period. Military vehicles, boats and helicopters were used to pluck stranded residents from their homes and vehicles. Florida Gov. Rick Scott said that officials received around 300 calls for rescue from stranded residents.

Two vehicles plummeted 25 feet after water caused portions of a highway to collapse. A 10-mile stretch of I-10 was also closed due to flooding, leaving people stranded for hours.

Gov. Rick Scott declared a state of emergency for the panhandle due to the impacts.

Unfortunately, Betty Faye Word, a retired school district employee, died when she drove her Mercedes into floodwaters just north of Pensacola.

Flooding at an Escambia County Jail may have contributed to a gas explosion that killed at least two people and injured more than 180 others. Escambia County's public information officer, Kathleen Castro, said she didn't know if flooding was the cause, but the jail did experience heavy flooding Tuesday and Wednesday. Preliminary investigations into the explosion indicate that flooding may have sprung a gas leak in a laundry room at the prison, sparking the explosion, but the investigation is still ongoing.

Georgia

Police blame a storm packing powerful winds for the death of a man in Athens. Athens-Clarke County Police Maj. Mike Hunsinger says strong winds Wednesday morning pushed over a tree that crashed atop a car, killing the driver. He said the death occurred at a mobile home park at about 6 a.m. as storms tore through the county, downing tree limbs and power lines.

Residents in Troup and Heard counties continued to clean up from a confirmed tornado Monday night. The tornado carved a 5.5-mile path of damage across western Georgia. A survey crew at the National Weather Service announced Tuesday that the twister was an EF2, packing winds as high as 120 mph.

Iowa

Authorities in southeastern Iowa say two people are dead and others are injured after powerful storms swept through the state.

One tornado was spotted northeast of Mount Vernon, Iowa, Sunday afternoon. The other tornado was spotted in a field north of Floris, Iowa. At least one farm near Wapello sustained damage to the roof and porch.

The Keokuk County Sheriff's Office confirmed two fatalities from Sunday's storms. Pam Ledger died Tuesday morning from injuries sustained after a barn collapsed in Keokuk County. Another person died Sunday when strong winds caused an outbuilding to collapse in a rural area near Kinross. That person's identity has not been released.

South of Udell, several farm buildings were damaged or destroyed as the storms moved through. Several trees about one-foot in diameter were snapped off. The roof of the Oskaloosa Family Medical Center in Mahaska was damaged.

Kansas

A tornado that tore through the southeastern Kansas town of Baxter Springs left 25 people injured and more than 100 homes and businesses damaged but caused no serious injuries or deaths, Cherokee County Sheriff David Groves said. The tornado was given a preliminary EF2 rating by the National Weather Service on Monday.

Nine of those injured when the storm hit Sunday evening were hospitalized with injuries that are not considered life-threatening. A person who died Sunday night suffered from a medical condition and the death was not attributed to the storm, he added.

The storm did damage ranging from minor to total destruction of 100 homes and 12 businesses in the town of about 4,200. The storm, which Groves said was 2 miles long and 2 blocks wide, also left behind mounds of debris, twisted metal, hanging power lines and residents grateful to have survived.

The tornado struck around 5:45 p.m. Sunday, cutting a diagonal through the town of about 4,200 people. Baxter Springs is located about six miles north of Quapaw, Oklahoma, where the same tornado struck just before hitting the Kansas town.

Kentucky

The National Weather Service has determined that injuries and damage in Harlan County were caused by 90 mph straight-line winds. The weather service said the storm on Monday caused three minor injuries and damaged three buildings in Evarts, including one building hit by a tree. Numerous trees were also reported damaged. Harlan County Emergency Management Director David McGill said the storm also downed power lines and caused power outages in the county.

Louisiana

A tornado touched down in rural northwest Louisiana around 3:15 a.m. on Monday, injuring one teenager and severely damaging his home. In northwest Louisiana, a teenager suffered minor injuries when a tornado touched down there early Monday. Bill Davis, a spokesman for the Bossier Parish Sheriff's Office, said the tornado hit around 3:15 a.m. Monday, about six miles west of Plain Dealing, in mostly a rural area. The teen suffered cuts and bruises and his home was heavily damaged.

Maryland

Emergency officials in Maryland say crews have rescued motorists who got stranded in high water on closed roads as heavy rains bring flooding to the mid-Atlantic region.

Road closures were reported due to flooding, downed trees and electrical lines.

Evacuations were ordered in Laurel, Md. after two dams were opened to alleviate stress on the structures, causing flooding in the area. Hundreds of people were evacuated to hotels and a nearby community shelter, but the evacuation orders were lifted Thursday morning. Route 1 remains closed in the area due to flood waters.

Anne Arundel County Fire officials say swift boat rescuers pulled two men from a car in rising water after they drove around a barrier in Laurel. Prince George's County Fire officials say rescuers in a boat pulled another man from a vehicle in Bowie.

Mississippi

At least nine tornadoes struck Mississippi on Monday, including an EF4 or stronger in Louisville and EF3 tornadoes in Tupelo and Richland, the National Weather Service said Tuesday. Six of the eight in central Mississippi were confirmed by radar signatures for debris but had not been checked by ground crews, said Daniel Lamb, a meteorologist in the weather service's Jackson office. They were generally along Interstate 20 between Vicksburg, Jackson and Meridian, he said.

"There may be more than that. Those are just the ones that we're aware of from the radar," he said.

Lamb said damage was still being assessed both in Lewisville and for the 4-mile track from Richland through Pearl. The tornado that hit Tupelo left a 24-mile-long swath from 7 miles south-southwest of Tupelo to the town of Ozark in Itawamba County, said Marlene Mickelson, a meteorologist in the service's Memphis, Tenn., office. Meteorologists thought at first there had been two tornadoes in north Mississippi, she said. "We determined it was just one with a long track."

Lamb said twisters identified by radar were southeast of Vicksburg in Warren County; north of Utica in Hinds County; north of Bolton, which is 20 miles north-northeast of Utica, in northern Hinds County; near Lake Caroline in Madison County; from Forest in Scott County to north of Lake in Newton County, a 9-mile track; and south of Decatur in Newton County.

Missouri

New York

The same system that dumped record rainfall on the southeast triggered flooding and a mudslide in New York. The mudslide occurred at the Metro North Glenwood Station in Yonkers, N.Y. Wednesday night, burying two tracks at the station. More than five inches of rain have fallen at New York City's Central Park.

North Carolina

A strong line of storms moved across central North Carolina Wednesday, bringing high winds and flooding rains.

A survey team with the NWS confirmed an EF1 tornado hit the town of Stedman, east of Fayetteville, on Tuesday, packing winds as high as 95 mph.

Flooding was reported in Fayetteville, where 74 people were rescued from flooded vehicles and homes Tuesday.

Two people were taken to a hospital. There was no immediate word on their conditions. Fire department officials said lightning strikes caused two fires. A number of roads were closed for a time, but most of those were open Wednesday morning. Seven buildings at Fayetteville State University suffered flooding on the ground floors.

Ohio

A series of strong storms that swept through central Ohio brought high winds and scattered reports of damage. The storms late Tuesday were part of a powerful weather system that spawned fatal tornadoes in the South.

Winds picked up and flipped a mobile home in the community of Bellville in Richland County, south of Mansfield. In Delaware, just north of Columbus, a roof was blown off a downtown building and onto a car parked on the street. Downed tree limbs also closed a road in Delaware. Scattered power outages were reported in central Ohio overnight.

Heavy rain also led to flash flood warnings for parts of central and southeast Ohio early Wednesday.

Oklahoma

Oklahoma Gov. Mary Fallin declared a state of emergency Monday for Ottawa County following a tornado that struck Quapaw, killing at least one person and injuring six. Monday afternoon, an NWS survey crew rated the tornado as an EF2.

John L. Brown, 68, was killed after a concrete wall fell on his car, trapping him and his wife. The couple were driving through downtown Quapaw when the tornado struck. The two sought shelter in a parking lot, according to the Ottawa County Sheriff's Department, but high winds brought down a nearby wall onto their vehicle. Mr. Brown was pronounced dead at the scene. Mrs. Brown was rescued from the vehicle, treated at a nearby hospital and later released.

Fallin says the state is prepared to offer every resource available to assist with the cleanup, rebuilding and recovery. The town of about 900 residents suffered heavy damage from the tornado, Ottawa County Emergency Management Director Joe Dan Morgan said.

The tornado damaged or destroyed about 60 buildings in the town of 900, including Quapaw's volunteer fire department station and a bank, reported News9.com.

Pennsylvania

Unusually heavy rains drenching much of Pennsylvania from a slow-moving storm have led to flooding, road closures and flight delays.

In Chester County, more than six inches of rain led to more than 62 overnight water rescues from vehicles alone. Three people were also rescued from the homes and around 100 roads were closed in the county Thursday morning.

Buildings were evacuated in Bucks and Montgomery Counties Wednesday and Thursday. Three people were rescued from the roof of a bus in Philadelphia after it got stranded in several feet of water Wednesday night.

Tennessee

The National Weather Service confirmed two tornadoes touched down in Lincoln County Monday. One tornado started near the Alabama line and cut a path to the northeastern corner of the county, leaving two dead and at least 25 homes and one elementary school destroyed.

"It was very chaotic for several hours," Lincoln County Sherriff Murray Blackwelder said. "By the grace of God, we were able to get by with only two fatalities out of this mass destruction."

Authorities identified the victims as John and Karen Prince. They were killed when their mobile home was thrown several hundred yards from its foundation.

The National Weather Service has not yet made a final call on the on the strength of the tornadoes, but set a preliminary ratings of EF3 and EF2.
